Berlin's Tiergarten is a city park which offers welcome relief from the unrelenting city architecture and general rudeness of the Berlin city. No matter the traffic, including tourist buses passing between Berlin landmarks peeking through the depressing grey gloom.
The origin of the Großer Tiergarten is as a royal park for hunting. My little hike would have been much more lively with a European bear or two around, rather than just statues, squirrels, birds, ducks and sleeping bats. And sunshine!
